She is versatile indeed. In some of the photos, specialy in the last three, she looks like an angelical frail creature. But in most of the photos she looks like an evil tempting succubus. I go for the second, darker side. It's mesmerizing.
I think that the blonde washes her features out too much, making her morph into the dozens of other models with similar peroxide coloured hair. Though the black hair makes her really stand out, in my opinion, and makes a great combination with her otherwise very innocent face, giving just the right amount of roughness/edge to her look.
